I have set of points (3D). What i am doing is getting a line that connect first and last point of data set. Then trying to find index of point that has max distance from line. Just to express my problem .

I wrote a function for that which usesEigenlibrary. Which is as below

Code :std::vector<Eigen::Vector3f> points; // input set of points typedef Eigen::ParametrizedLine<float, 3> Line3; static Line3 start_to_end = Line3::Through(points[0], points.back()); float max_dist_squared = 0.0f; size_t max_idx = 0; for (size_t i = 0; i<points.size(); ++i) { float dist2 = start_to_end.distance(points[i]); if (dist2 > max_dist_squared) { max_dist_squared = dist2; max_idx = i; std::cout << "\n Distance is " << dist2 << " and i " << i << std::endl; } }

PROBLEM : I want to write same method using GLM. I mean to ask is any method that help me to findlineand distance from a point. Or how can i convert above code Using GLM library.
